RIBBON-ATTACHING MEAN S FOR TYPE-WRITERS.

Patented July 29, 1919.

Original application filed July 10, 1917, Serial No. 179,665. Dividedand this application filed September 9,

1918. Serial No. 253,254.

To all whom it may concern:

Be it known that I, J OHN A. HAGERSTROM, a citizen of the United States,and resident of Scranton, in the county of Lackawanna and State ofPennsylvania, have invented certain new and useful Improvements inRibbon-Attaching Means for Ty e-Writers, of which the following is aspool cation.

This invention relates more especially toribbon spools for typewritersand has for its principal object to provide improved means of simpleandeflective construction for detachably connecting the end of atypewriter ribbon to the spool upon which it is wound. The presentinvention constitutes a division of my copending ap lication seriallynumbered 179,665, filed uly 10, 1917. According to the preferredembodiment of my invention shown in the drawings in which- Figure 1 is atransverse. section of a spool constructed accordingtto the presentinvention;

Fig. 2 is a side elevation of the same from one side;

Fig. 3 is a side elevation of the same from the opposite side, partsbeing broken awa Fi 4 is a side elevation of a bodkln whic may beemployed in connection with my improved ribbon attaching means.

Referringmore particularly to the drawing, a ribbon spool s indle 1 isprovided with an annular shoul er 2 which is adapted to support the hubportion 3 of a ribbon spool which. has a cylindrical drum 4arrangedbetween the spaced circular flan 5-. The drum 4 is provided with a'relatlvely narrow slot 6 and a relatively wide slot 7, said slots beingpreferably arranged on opposite sides of the axis of the spoolandsubstantially. parallel to the axis thereof. The

edges of the relatively narrow slot 6 are provided with arcuate recesses8 to permita bodkin 9 such as that shown in Fig. 4. Said bodkin'9 isadapted to be inserted between the arcuate recesses 8 until it protrudesthrough the relatively wide slot 7 and beyond the outer wall of the drum4. The bodkin in this position is now ready to receive between its jaws10, a buckle .11 secured to the end of a tape 12. Said tape is providedon its other end with an anchor or enlargement 13 which is of a size topass readily through the relatively wide vslot 7 but is too large 'to bedrawn through the smaller slot 6. After the tape 12 has thus becomeanchored on the edges of the smaller slot, it is ready to have thetypewriter ribbon attached thereto by means of the buckle 11. I

I claim:

1. In a typewriter, a ribbon spool comprising axially spaced flanges,a'hollow drum uniting said flanges and provided with a slot or opening,a ribbon adapted to be threaded through said slot or opening, and meansattached to the end of said ribbon for anchoring it within said drum onthe edges of said slot or opening.

2.' A'typ'ewriter spool comprising a cylindrical drum provided with anaxial slot in the wall of said drum, and a ribbon attaching tapeextending through said slot and .having an enlargement on its inner endto prevent its retraction from within said drum, said drum beingprovided with recesses along the edges of said slot for permitting theintroduction of a bodkin for-drawing said tape through the slot.

3. A typewriter spool, comprising a cylindrical drum provided with anaxial slot in the wall of said drum, flanges at either end of said drum,and a ribbon attachin tape extending through said slot and having anenlargement on its inner end to prevent its retraction from within saiddrum, said drum being provided with another axial slot of greater widthfor permitting such enlargement to be drawn into said drum.

4:; A ribbon spool provided with flanges and a drum extending betweensaid flanges, said drum bein provided with o positely arranged axial sots of different wi ths, and

a ribbon-attaching tape provided with an
